<p>An electric connection box comprises a circuit casing consisting of a case for containing a circuit structure and a cover, a lower connector housing arranged on the lower surface side of the circuit casing and connectable with an external connector, and a plurality of bus bar lower edge side terminals for electrically connecting the circuit structure and the lower connector housing. The bus bar lower edge side terminal is taken into the housing from the ceiling portion of the lower connector housing through a route traversing the circuit casing in the horizontal direction. A waterproof wall covering the upper part of the ceiling portion is provided in the circuit casing. Thus, water intruding into the circuit casing drops onto the waterproof wall and does not reach the ceiling portion of the lower connector housing on the underside thereof. Consequently, it is possible to prevent pooling of water at the ceiling portion to cause short circuit between the lower edge side terminals of bus bars routed through the ceiling portion.</p> |
